1. The Triangle Math and Science Academy School is not co-ed
2. Operates on the campus of William Peace University (Liberal Arts en.wikipedia.org/wiki/Peace_College)
3. Depends on where you live, since I live in West Cary this was a long ride to Raleigh Downtown.
4. Wake County Public schools are very good.

I believe TMSA is coed. Where did you hear it's not? With regard to location, it's supposed to be relocated from Raleigh to Cary. As for the OP, kinda late for these questions if you have already opted to enroll.
